2026-04 Monthly Summary: Delivered two major feature refactors across the DUNE software stack to support detector simulation modernization and G4Beamline integration. Key outcomes include a modular DUNE Simulation Noise Modeling and Signal Processing Framework in dunesim, and a Channel Mapping Service for the G4Beamline refactor in dunecore, complemented by build/configuration improvements. These changes enhance configurability, performance, and maintainability, align with downstream simulation workflows, and reduce integration risk. No explicit bug fixes were documented for this month; the refactors lay groundwork for future bug fixes and feature iterations, improving overall stability and collaboration across repos.

March 2026: Focused on enhancing the DUNE LAr TPC simulation pipeline (dunesim). Implemented noise addition services, improved signal processing modules, and integrated configuration management to raise simulation accuracy and data acquisition performance. Also merged a critical beam generation fix (PR #104) to correct beam momentum orientation, ensuring consistent physics cases across simulations.

May 2025 monthly summary focused on delivering a robust, unified data filtering path for the DUNE/dunereco reconstruction pipeline by integrating WireFilter-based filtering. This work replaces the legacy HitFilter, aligns build/config with the new filtering stage, and adjusts the default valid TPC range to improve data quality and reliability in reconstruction workflows. The changes reduce maintenance overhead and set the foundation for consistent, high-quality input data across runs.
